@ernspiker, Had you done a simple search on the Publicmobile forums you would have had an instant answer rather then making a thread and waiting for replies
If you're an existing customer looking for a replacement SIM card follow the instructions posted here
If you're looking to join Public Mobile you can enter your email address at the BETA page and Public will notify you when you are selected to join the BETA program after which you will be sent a SIM card.
